OFFSHORE, MOORING SYSTEM<br />
Application<br />
A moored ship, like an FSO, is almost constantly in motion. This means that fatigue must be taken<br />
seriously, especially in all parts connecting the ship with the ocean-floor. Most motions take place<br />
in the connection of ship and anchor chain and reduction in torque there directly reduces the demands<br />
on steel parts. To reduce friction now D-glide bushings are used in the first uni-joint instead<br />
of self-lube bronze bearings or steel-on-steel. With D-glide bearings shaft diameters can be reduced.<br />
In spite of the almost continuous motions, the always present loads and the reduced dimensions,<br />
expected bearing life is still more than 20 years.<br />
Advantages of the D-glide solution<br />
- low torques<br />
- maintenance free<br />
- large reduction in component weight<br />
- large cost reduction<br />
- no corrosion problem<br />
